RFID Member Info Portal

Introduction

Section titled “Introduction”

The RFID Member Info Portal Project is intended to primarily provide a method for members to use the RFID cards and key fobs to lookup information about their Active Directory Account at Dallas Makerspace, including Voting Rights and Machine Use Rights.

The system will be open source and will use off the shelf components as much as possible.
